SA Tuning was founded in 2010 by the owner and current Technical Director Simon Sweetland. Initially SA Tuning was completely focused on ECU remapping and performance tuning. Over the years the company has evolved and we now offer a range of technical services, which can be divided into four main categories:

ECU Remapping

The true potential of a vehicle can be unleashed with ECU remapping.  Depending on customer requirements, this could be extracting as much performance as possible, or generating greater fuel efficiency. All our maps are fully custom and are developed in house on our V-Tech DYNO (rolling road). We cover all sectors including automotive, HGV, agricultural and marine engines. 

Vehicle Modification

This ranges from performance exhaust systems, induction kits, Intercooler supply and fitting, engine transplants, to turbo upgrades.  We develop solutions to bypass the often-unnecessary components and features installed on modern automotive vehicles. This can be for performance reasons or simply as a more cost-effective solution to replacing a faulty component. E.g. Bypassing the EGR system and the software in the ECU to improve fuel efficiency and reduce maintenance costs.

DPF Solutions

We have vast experience with the often misunderstood DPF systems on modern diesel vehicles, and can offer a wide range of services depending on the customer’s requirements. These include cleaning, removal and replacement.  We can offer you a professional, technical and informative solution to suit your needs. 

Diagnostics and Programming

Continued investment in the latest aftermarket and main dealer diagnostic equipment allows us to offer everything a dealership can do and more. Our tools can access a level of ECU interrogation that even main dealerships can’t achieve. From fault finding to module programming and initialization, to software roll back and more.

Our Dedicated Tuning facility

We have a 2500 square foot dedicated tuning Facility located in Great Hallingbury, Hertfordshire, on the Hertfordshire – Essex border on the outskirts of London. We are very close to the M11 and M25. Within this workshop we carry out all DPF related work, ECU Remapping, diagnostics and vehicle modifications. Our Hi-Tech Dyno (rolling road) is located at our tuning facility and is used for research and development, as well as dedicated custom tuning.
